Description

用于扬声器模组的壳体、扬声器模组以及电子设备 技术领域
本发明涉及电声转换技术领域，更具体地，本发明涉及一种用于扬声器模组的壳体、扬声器模组以及电子设备。
背景技术
在现有技术中，矩形扬声器单体通过四条侧壁与模组壳体的四条挡壁进行定位。除了定位之外，还需要在侧壁与挡壁之间的间隙涂粘结剂，以进行矩形扬声器单体的粘接固定。由于侧壁与挡壁之间的间隙较小，故粘结剂很难渗透到间隙中。这样会造成扬声器单体的粘接面积小，粘接强度低。扬声器单体容易脱落。
此外，这种定位方式对挡壁的加工精度要求高，稍微有偏差就会造成定位不准或者扬声器单体安装不到位。
此外，挡壁的长度大，与扬声器单体接触面积大，定位操作难度大。
发明内容
本发明的一个目的是提供一种用于扬声器模组的壳体的新技术方案。
根据本发明的一个方面，提供一种用于扬声器模组的壳体。在所述壳体上设置有定位角和挡壁，所述定位角和所述挡壁围合，以形成用于安装扬声器单体的安装部，所述定位角被配置为与所述扬声器单体的角部相匹配，以对所述扬声器单体进行定位，所述定位角与所述角部之间具有定位间隙，所述挡壁与所述扬声器单体的侧壁相对，所述挡壁被配置为用于与所述扬声器单体之间形成涂胶槽，所述涂胶槽的宽度大于所述定位间隙的宽度。
可选地，在所述安装部内设置有用于与所述扬声器单体的振膜的边缘进行粘接的涂胶带，所述涂胶槽的底面与所述涂胶带位于同一平面。
可选地，所述涂胶槽的底面的宽度与所述涂胶带的宽度之和大于或者等于0.8mm。
可选地，所述扬声器单体为矩形，所述定位角为2个，2个所述定位角分别与所述扬声器单体的2个相对的角部一一对应，以进行定位。
可选地，所述扬声器单体为矩形，所述定位角为3个，3个所述定位角分别与所述扬声器单体的3个角部一一对应，以进行定位。
可选地，所述扬声器单体为矩形，所述定位角为4个，4个所述定位角分别与所述扬声器单体的4个角部一一对应，以进行定位。
可选地，所述壳体包括第一外壳和第二外壳，所述第一外壳和所述第二外壳相互连接，在所述第一外壳或者所述第二外壳上设置有所述安装部。
可选地，所述定位间隙的宽度为0.03-0.05mm。
根据本发明的又一个方面，提供了一种扬声器模组。该模组包括扬声器单体和本发明提供的所述壳体，所述扬声器单体被设置在所述壳体的安装部中。
根据本发明的又一个方面，提供了一种电子设备。该设备包括本发明提供的所述扬声器模组。
本发明的一个技术效果在于，本发明实施例的壳体，通过设置定位角，对扬声器单体进行定位，挡壁不起到定位作用。由于定位角与扬声器单体的接触面积小，所以定位操作难度小，并且定位精度高。
此外，挡壁与扬声器单体之间形成涂胶槽。由于挡壁不起到定位作用，所以涂胶槽的宽度可以根据需要做的更宽。涂胶槽能够容纳更多的粘结剂。通过这种方式，扬声器单体与壳体的粘接力显著增强。
此外，由于定位角与扬声器单体接触面积小，挡壁与扬声器单体16之间具有足够的空间，故当扬声器单体的侧壁向外局部变形时，也能够安装到安装部中。通过这种方式，扬声器单体的装配难度显著降低。
此外，扬声器模组装配的成品率显著提高。
通过以下参照附图对本发明的示例性实施例的详细描述，本发明的其它特征及其优点将会变得清楚。

具体实施方式
现在将参照附图来详细描述本发明的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术和设备可能不作详细讨论，但在适当情况下，所述技术和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
根据本发明的一个实施例，提供了一种用于扬声器模组的壳体。如图1-4所示，在该壳体上设置有定位角12和挡壁13。例如，定位角12包括用于形成设定夹角的两条边。
定位角12和挡壁13围合，以形成用于安装扬声器单体16的安装部。例如，安装部的形状与扬声器单体16的外部轮廓相匹配。例如，安装部为矩形或者其他多边形。
定位角12与扬声器单体16的角部18相匹配，以对扬声器单体16进行定位。例如，定位角12的夹角与扬声器单体16的角部18的角度一致，例如，二者均为直角、锐角或者钝角。当扬声器单体16组装到安装部之后，扬声器的角部18位于定位角12的内侧。
定位角12与角部18之间具有定位间隙14。例如，定位间隙14为定位角12的边与相应的角部18的外表面之间的距离。定位间隙14越小则扬声器单体16的定位精度越高，并且扬声器单体16的安装越牢固。
优选的是，定位间隙14的宽度为0.03-0.05mm。该尺寸能够保证扬声器单体16在安装部中的定位准确。
挡壁13与扬声器单体16的侧壁17相对。挡壁13被配置为用于与扬声器单体16之间形成涂胶槽15。涂胶槽15的宽度大于定位间隙14的宽度。
在扬声器单体16安装到安装部后，需要在涂胶槽15内涂覆粘结剂，例如单体密封胶。在固化后，粘结剂获得粘接力。这样，扬声器单体16被固定在安装部中。
例如，涂胶槽15为上、下贯通的通径，如图3所示。
例如，涂胶槽15为开口端向下逐渐减小的结构，以容纳更多单体密封胶，如图6所示。
例如，涂胶槽15非贯通的结构，其中，涂胶槽15开设在挡壁13的上侧，以容纳更多单体密封胶，如图7所示。
本发明实施例的壳体，通过设置定位角12，对扬声器单体16进行定位，挡壁13不起到定位作用。由于定位角12与扬声器单体16的接触面积小，所以定位操作难度小，并且定位精度高。
此外，挡壁13与扬声器单体16之间形成涂胶槽15。由于挡壁13不起到定位作用，所以涂胶槽15的宽度可以根据需要做的更宽。涂胶槽15能够容纳更多的粘结剂。通过这种方式，扬声器单体16与壳体的粘接力显著增强。
此外，由于定位角12与扬声器单体16接触面积小，挡壁13与扬声器单体16之间具有足够的空间，故当扬声器单体16的侧壁17向外局部变形时，也能够安装到安装部中。通过这种方式，扬声器单体16的装配难度显著降低。
此外，通过这种方式，扬声器模组装配的成品率显著提高。
优选的是，如图3所示，在安装部内设置有用于与扬声器单体16的振膜的边缘23进行粘接的涂胶带19。例如，振膜包括折环，振膜的边缘23由折环向外延伸形成。涂胶槽15的底面22与涂胶带19位于同一平面。通过这种方式，能够增加粘结剂涂覆的宽度，提高粘结剂与壳体的附着力。
例如，在扬声器单体16安装时，首先，在涂胶带19和涂胶槽15的底面22涂覆单体固定胶；
然后，将扬声器单体16放置到安装部中，其中，振膜的边缘23与单体固定胶接触；
最后，在涂胶槽15内涂覆单体密封胶。
在固化后，单体固定胶使壳体与振膜的边缘23之间形成粘接力；单体密封胶使扬声器单体16的侧壁17与挡壁13之间形成粘结力。
此外，单体密封胶还起到密封扬声器单体16与挡壁13，以及扬声器单体16与定位角12之间的空隙的作用。
单体固定胶的宽度越大则粘结强度越高。然而，受电子设备小型化的要求所限，涂胶带19的宽度通常较小。在该例子中，涂胶槽15的底面22与涂胶带19位于同一平面。通过这种方式，增加了涂覆粘结剂的区域的宽度。在涂覆单体固定胶时，可以使单体固定胶同时覆盖涂胶带19和涂胶槽15的底面22，以获得更大的粘结力。
优选的是，涂胶槽15的底面22的宽度与涂胶带19的宽度之和大于或者等于0.8mm。该尺寸能够保证扬声器单体16与壳体之间具有足够的粘 接力。
在一个例子中，扬声器单体16为矩形。矩形的扬声器单体16包括四个角部18。定位角12为2个。2个定位角12分别与扬声器单体16的2个相对的角部18一一对应，以进行定位。通过这种方式，两个相对设置的定位角12能够限定矩形的扬声器单体16沿平行于扬声器单体16的延伸方向的位置。例如，延伸方向为垂直于振动方向的方向。
在另一个例子中，扬声器单体16为矩形。定位角12为3个。3个定位角12分别与扬声器单体16的3个角部18一一对应，以进行定位。三个定位角12中的两个相对设置，以对扬声器单体16的相对设置的角部18进定位。另一个定位角12对第三个角部18进行定位。通过这种方式，三个定位角12能够限定矩形的扬声器单体16沿平行于扬声器单体16的延伸方向的位置。
在又一个例子中，如图1所示，扬声器单体16为矩形。定位角12为4个，4个定位角12分别与扬声器单体16的4个角部18一一对应，以进行定位。通过这种方式，4个定位角12能够限定矩形的扬声器单体16沿平行于扬声器单体16的延伸方向的位置。4个定位角12使得扬声器单体16在安装部中的定位精度更高。
在一个例子中，如图5所示，壳体包括第一外壳11和第二外壳20。第一外壳11和第二外壳20相互连接。在第一外壳11或者第二外壳20上设置有安装部。通过这种方式，扬声器单体16的拆、装更方便。
例如，在第一壳体上设置有定位角12和挡壁13，二者围合形成安装部。在第一外壳11内还设置有用于与振膜连通的出声孔。
例如，在第二壳体上设置有定位角12和挡壁13，二者围合形成安装部。在第二外壳20内还设置有用于与振膜连通的出声孔。
例如，通过注塑成型的方式将定位角12和挡壁13与第一壳体，或者将定位角12和挡壁13与第二壳体一体成型。一体成型的方式能使定位角12、挡壁13与第一壳体，或者定位角12、挡壁13与第二壳体的连接强度更高。
根据本发明的另一个实施例，提供了一种扬声器模组。该模组包括扬 声器单体16和本发明提供的壳体。扬声器单体16被设置在壳体的安装部中。
例如，如图5所示，壳体包括扣合在一起的第一外壳11和第二外壳20。在第一外壳11上设置有安装部和用于出声的出声孔。扬声器单体16通过设置在壳体内的FPCB21与外部电路电连接。
该扬声器模组具有连接强度高、耐用性良好的特点。
根据本发明的又一个实施例，提供了一种电子设备。该电子设备包括本发明提供的扬声器模组。
该电子设备具有声音效果好、耐用性好的特点。
虽然已经通过示例对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
